New York, NY: IPTComm 2007 at Columbia University was organized by Henning Schulzrinne, one of the co-inventors of SIP and an ongoing developer of VoIP applications. Schulzrinne commented that he thinks one of the big reasons people aren't developing new communication services is because there's nothing like PHP that can control calls.
He's referring to the PHP programming language, which was one of the first widespread ways that people wrote programs to develop web applications. Perl programming of CGI web applications came earlier, but required integration with Apache and mod_perl. PHP came out-of-the-box ready to do web pages. It was simple to do simple things, and possible to do harder things.
